Environment: 2.74 dc15860 Win64 (after triangulation fix to 2.75-testbuild1)

Sorry, but this one has come back. The following clarifies when it happens and may explain earlier failure to reproduce and mistaken impression that it was fixed. With any luck, it's just a simple loop counter problem.

Reproduction:
(1) Open default file;
(2) delete lamp and camera;
(3) UV unwrap default cube;
(4) Export Collada with default options (dae1);
(5) Export Collada with Only Selected UV map checked (dae2);
(6) Add another UV map, select it and unwrap;
(7) Export Collada with Only Selected UV map checked (dae3);
(8) Select the first UV map;
(9) Export Collada with Only Selected UV map checked (dae4);

Expected: All exported dae files have one UV map.
Observed: dae2 and dae 3 have no UV map. The others do have one.

More generally: However may UV maps are added or removed, whenever the selected UV map is the last in the list and the Only Selected UV map option is checked, no UV map is exported. All UV maps are exported when the option is unchecked.

The calculation of the UV maps for export used a wrong method to get the index of the active UV Map.
This was due to a misunderstanding of how the API works.
I think now it is really fixed.

Sorry for the mistake.
